Global Position System (GPS) technology can be used to meet outdoor application needs. However, GPS signal is blocked by buildings, thus other positioning solutions have to be resorted. Wi-Fi with fingerprinting is a viable and reliable approach, but it usually takes too long to set up the construction and is quite hard to update devices. With the introduction of iBeacon in 2013, sensors based on Bluetooth 4.0 show high reliability and low cost. iBeacon may become a better solution for indoor positioning system. This study focuses on verifying feasibility to indoor-location by using iBeacon and analyzing differences between positioning methods. We design and implement an application on smartphone to test positioning methods and to analyze the advantages and problems of these methods in different indoor space. We also propose and implement a new hybrid method to reduce the equipment cost and the setup time. The result proves that is feasible to build a positioning system using iBeacon. It has the accuracy similar to positioning using Wi-Fi. We also found that each positioning method has its own advantages can be implemented in different spaces. If we implement those method by combination solution, we will get better positioning results. Comparing with Fingerprinting, the method with best positioning accuracy, the combination method we proposed increases the distance error by 12%, while reduces the equipment use by 50% and the setup time by 56%.
